devices and particularly to lsuch devices whichare used for pumpinga number of oil wells from a single point, orstation, at the same time. It is customary for such machines to be in constant operation, day and night, and it is, therefore, necessary for them to be constructed with a view to great durability. It is also necessary for them tovbe thoroughly lubricated at all times and of simple construction, so as to prevent mishaps necessitating the'shutting down of the mechanism with a resultanthalt in the pumping.'l As it is customary to pump ya large number of wells with oneapparatus it will be readily understood that a stop, for repairs, for a comparativelyishort time, .would result in a material pal object ofthis invention to provide a con:

struction possessing durability and simplicity with means vforvthoroughly lubricating the parts-at allrtimes, from a ksingle `source and without wastage, andwhich willprevent foreign matter from entering the working parts. Y 4 Y Another object is to providea construction which will bey-compact, readilyaccessible with respect to its various parts, and Vthat will occupy a minimum amount of space.

' Other objects and advantages will be .ap-

parent from'the following description lwhen taken in connection with the accompanying drawings. t

- In the drawings:

Figure 1 is a vertical'rsectional view of a` view illustrating certain horizontal oil ducts in the retaining ring.

Referring particularly to the .accompanying drawings, represents a housing in which is mounted a horizontally disposed w-orm-shaft 11,and a vertical shaft 12. r Secured to the lower end of the shaft 12, within the housing 10, is a worm-wheel 13, which meshes with and is driven by thel worm-shaft 11. Keyed on the shaft 12, above the Vhousing 1C, and arranged in superimposed spaced relation'to each other, are the eccentric'inem bersx14 land 15, each having a hub portion 16, a; channeled rim portion 17, and a series of connectingV spokes 18. Upon reference to Figure 1 it will be notedthat the major portions of the members 14 and 15 extend in diametricallyOppositek directions from the shaft 12. The upper face of the bottom wall Vof the rim portion of the member 14 is formed with the steps 20, 21 and 22, while the outer or marginal wall constitutes an upwardly and outwardly extending flange,y 17a', having an inwardly directed. circumscrib-ing rib 17 at its upper edge. It will be noted that the marginal wall of the ring 19, adjacent the flange 170;, is inclined .tocon-y form therewith and spaced slightly therefrom. This is Vfor a purpose that will be later set forth. Disposed within the channel of the member 14 is a power ring 19, having the shoulders 1.9 and 23 on its lower face which rest, respectively, on the steps I .and

22. It will 4be noted that these shoulders result in .an annular groove 24, whichever-'lies the step '21, lwhereby to provide an oil channel to receive an accumulation of oil to .be supplied to the adjacent parts. Theperiphery of the power ring is formed with an .eX-

tension bead or rib which extends over` the upper face of the flange 17 a, to prevent entrance of foreign matter at this point.

To maintain the power ring 19 properly channeled rim 17, with its head yoverlying the powerri-ng 19 andtheinner wall of the` channeled rim 17. rlhis retaining ring 26 is secured to the said inner wall by means of screws 27, and between the meeting faces a paper, or other suitable gasket 27a is employed. @n the upper face of this inner wall there is formed a vertical bead 28, while a similar bead 29 is formed on the upper face of the power ring 19, and between these headstne said head of the retaining Aring 26 is 'disposed T he beads 28 and 29 are to pre-v vent oil from flowing on the upper surfaces of the adjacent parts on which they. are formed. V

Formed on the upper Aface ,ofY the power ring 19 are the upwardly extending studs 1 upper end of the stud.

'Disposed on the upper end of the bolt, and arranged within the upper end of the sleeve 35, is a beveled disk 38, aV nut 39 being engaged on the boltrto properly clamp f the partsk together, butl permitting freerotation olf .the sleeve on said stud.l Extending laterally from the sleeve 34 is a clamp 40, in which is secured one end oflone of the pumping rods 41.

Formed in the face of the inner wall of the channel of the rim 17 is a circ-umscribing oil groove 42, and in the adjacent face of the stem of the retaining ring 26 there is formed asimilar groove 42, such grooves being at the same level, and cooperatingto form a circumscr'ibing channel. ln the inner face of thepower'r'ing 19, at the same level as the grcoves'j42 and 42', is a groove 43, said groove having communication with the grooveV 42', by means of a series of transverse oil passages V44, forinedthrough the vertical web 26 of the retaining ring 26. Extending from the groove 42, is an oil passage 45 which registers with the lower end of the vertical oil passages 46, formed inl the inner portion of the head of the retain.

ing ring 26. Properly secured in the upper end 'of the passage 46 is one end of an oil pipe or'conduit 47. Secured on the upper end of the shaft 12 is a sleeve 48, and formedon the upper end of said sleeve is a cup 49. Connected -to the bottom of said cup 49 is the other end of the before-mentioned pipe 47. It'lwill be noted that the pipe 47 leads to a point' of the eccentric member 14 near the shaft 12, through the retaining ring 26. `V`llt the upper end of the shaft 12, and properly fittedywithin the bearing 50, is the 'capnmember 51, for supporting saidY shaft. This cap is formed with an upwardly extending peripheral flange 52, through which are disposed, and'secured, the inner ends of the radially extending brace rods 53, said rods having their other ends engaged over the uprights anchored therebeyond.

Secured in the bottom wall of the member 51, is a suitable'lubricant container 57, preferably of the automatic gravity feed type. Passing throughthe step 22, of member 14,Y at Vja ,point-opposite-the passage 45, isV a vertical Voil" passage 58, and secured in the vlower. end of said oil passage is an oil pipe 59.

The'member 15 is of similar construction to that described in connection with the member 14, and has the power ring disposed in its channel,such ring vbeing held in the .channel by means of the retaining ring 61, and being provided with upwardly extendingstuds 31', constructed lin amanner similar to the studs 31, of the power ring 19. The power ring 60, and the inner wall of the channel, are formed, respectively, with the oil grooves 63 and 64, betweenwhich communication ,is established by means Vof the oil passages 60', formed through the vertical web of the retaining ring 61.` `The groove 64 has the vertical oil 'passage 65 whichregisters with the passages 66, in the head of the'v retaining ring 61. 'The lower end of the before-mentioned oil pipe 59 is secured within vthe upper end of this oil passage 66. The lower face of the power ring 60 is formed-with the'annularoil groove 67, similar to the groove 24, of the ring 19. Leading downwardly through 'the bottom of the channel of the member 15, from the ledge 68, is an oil passage 69, within which is secured one end of the oil pipe 70, said pipe having its other end secured in the outer end of the oil passage.`71, formed in thehub member 16 of the member 15, and which passage extends to a point directly above a bearing 7 2., which is located inthe upper'portion of the housing 10, and which surrounds the shaft 12. 1- The voperation of the lubricating system of the mechanism described herein, is as follows: From the lubricant container57 oil will flow tothe bearing l50 and thence tothecup 49. From the cup .49 is passes through the pipe 47, and the head of the retaining ring -26, to the t groove'42, through the passages 44, to the groove 43. *Hereit-lubricates the contacting faces of the retain-ingfring, and the power ring 19. The excess then gravitates to the bottom of the channel where :itflows over and lubricatesthe step 20 andthe lower face of the shoulder19, which rests thereon. It then reaches the annular groove 24, where it rises to the level shown in the drawings, and vflows over the steps 21 and 22, lubricating the lat ter, and also the contafctinglface of the shoulder 23. -AsI the oil is maintained at this level, in the groove 24, it will be seen that the lower portion of the power ring 19 rests in a bath of lubricant. As a result of centrifugal action, afquantity of the oil passes up theinner slanting wall of the flange 17a, but is prevented from escaping by the flange 17 b. Having reached the uppersurface of the step 21, the oil then flows through the opening 58, and the pipe 59, to the eccentric member .15, its power ring 60, and its retaining ring 61, which it lubrioates in the same manner as described in connection with the eccentric member 14, and its co-acting parts.

Passing from the eccentric member 14, through the pipe 70, the oil reaches the housing 10, where it lubricates the bearings 72 and 7 3, which support the shaft 12, the wormwheel 13, and the worm-shaft 11, with its bearings 74. Having thoroughly lubricated all of the wearing parts, the oil then accumulates in the housing 10 until it reaches a point determined by the cock 75, in the well known manner. Excess oil and sediment may then be drawn olf through the pipe 7 6, at the bottom of the housing 10.

It will be understood that the herein described mechanism will be operated from any suitable source of power which will be cennected to the worm-shaft 11. It will also be understood that any desired number. of pumps may be operated from the power rings 19 and 60, within the limit of the studs carried thereby. It will be further understood that numerous changes may be made in the construction of the various parts without departing from the spirit of the invention.
